Germany’s HeidelbergCement AG said Friday it will raise cement prices starting early 2007. Chief Executive Bernd Scheifele said Friday in a telephone press conference the company currently isn’t achieving a positive return on assets in Germany. 
 
In order to change this, the company must raise prices for cement by at least Euro 7 a tonne, he said.  According to Scheifele, the company hasn’t been able to pass on to its customers the 20 per cent rise in energy costs that occurred within the first half of 2006.
